Wait of 2 posters that i know saying." harry should outbox him based on their records and ranked fighters that they fough" lmao
Greb is not proven enough against the toughest HW hitters to pick him here. I'm sure that he would make Tua look like a fool for a few rounds, but he wouldn't win that fight. Way too small to compete.
This is actually a difficult one to call. Harry Greb beat some good heavyweights, and in some cases shut them out. He also clowned Dempsey in sparring by all accounts. What we never really saw however, was him up against a top end puncher like Tua, in an actual fight. Also without footage of him, it is hard to say exactly how elusive he was. It would be easier to favor somebody like Gene Tunney or Tommy Loughran here.
It’s quite conceivable that with his erratic unorthodox style that Greb could make things very uncomfortable for Tua. Tua would only need to catch him cleanly once though and it’s curtains.
Harry could probably outbox him for a number of rounds. But Tua can wear him down with his strength and size and ultimately land. Greb would have to survive on footwork and elusiveness, perhaps a la Byrd. He didn't possess the long powerjab that defused Tua. I still say Tua catches up to him after round 5 or 6 as he withers under Tua's pressure.
